    • A micro-extrusion printhead assembly utilized in a micro-extrusion system to form parallel extruded gridlines of material on a substrate includes a nozzle having a tapered (e.g., triangular or trapezoidal) cross-section arranged such that a lower surface of each gridline is substantially wider than its upper edge, and such that side surfaces of the extruded gridlines reflect incident light beams into exposed surface areas of the substrate, thereby minimizing the effective shadowed surface area under the gridline. In one embodiment, the fluidic channels of each nozzle are fabricated by cutting or etching progressively wider channels into a series of rigid layers, and then stacking the rigid layers to form a layered nozzle structure. In another embodiment, a single layer is processed to include a tapered cross-section having the desired triangular or trapezoidal cross-section.
    • 在微挤出系统中使用的微挤出打印头组件在基板上形成平行挤出的材料网格线包括具有锥形(例如,三角形或梯形)横截面的喷嘴,其布置成使得每个网格线的下表面基本上 并且使得挤出的网格线的侧表面将入射光束反射到衬底的暴露的表面区域中,从而最小化网格线下的有效阴影表面积。 在一个实施例中,每个喷嘴的流体通道通过将逐渐更宽的通道切割或蚀刻成一系列刚性层来制造,然后堆叠刚性层以形成分层喷嘴结构。 在另一个实施例中,处理单层以包括具有期望的三角形或梯形横截面的锥形横截面。
